Blumberg sign

Blumberg's sign is a sign that is elicited during physical examination in medicine. It is indicative of peritonitis.

The abdominal wall is compressed slowly and then rapidly released. A positive sign is indicated by presence of pain upon removal of pressure on the abdominal wall. It is very similar to rebound tenderness and might be regarded by some authors as the same thing, or at least a particular application of it.

The name comes from German surgeon Jacob Moritz Blumberg.[1][2]

Positive Blumberg sign or rebound tenderness is indicative of peritonitis. This method is specially useful in diagnosing appendicitis requiring urgent management.[3]
